GB 14317-1993

This standard specifies radiation protection requirements for the design, operation, and decommissioning of nuclear heat power plants, which are nuclear facilities that supply both electricity and thermal energy for district heating or industrial processes. It is applied in China to ensure that occupational workers, the public, and the environment are safeguarded against excessive radiation exposure during normal operations and potential accident conditions. The regulation covers dose limits, monitoring procedures, and safety measures specific to the combined power and heat generation context.
